The Girlfriending Test
This person and their girlfriend reached a new milestone in their relationship. After dating for a while, the OP invited his GF to stay over for the night. They had dinner together and probably watched a bit of Netflix before calling it a night. The next day, the girlfriend left his place, and that was that.
But that wasn’t that. This guy posted the mess she left in his crib and called her out for not being wifey material. Basically, he wanted to know whether she would clean his place after crashing there for a night. We think the OP failed the boyfriending test, if we’re being honest.
